And main and secondary beam nodes of fabricated concrete frame structure are connected

The utility model relates to main and secondary beam joint connection of a fabricated concrete frame structure. Stress steel bars are arranged in the bearing columns and connected with the main beams,inter-beam connecting pieces are pre-buried in the middles of the main beams, and the pre-buried inter-beam connecting pieces are fixed to steel reinforcement cages in the main beams. U-shaped connecting pieces are pre-buried in the left end and the right end of the secondary beam, and the concave connecting plates are connected with the inter-beam connecting pieces through bolts and fixed together with the inter-beam connecting pieces, so that the main beam is connected with the secondary beam; the lower end portion, the left end portion and the right end portion of the prefabricated shear wall are provided with wall outward-extending steel bars. And the prefabricated shear wall is connected with the bearing column and the main beam through overhanging steel bars on the wall. The prefabricated part is high in as
